A road-widening project has unearthed four new baleen whales species in Southern California's Laguna Canyon. The fossil specimens, at 17 to 19 million years old, are the most recently evolved toothed baleen whales yet discovered, reported ScienceNOW.

"The toothed cetaceans, which include killer whales, sperm whales, and dolphins, are though to have split off from the baleen whales about 35 million years ago.

Past findings have shown that soon after that split, mysticetes still had teeth. Even today, some baleen whales develop tooth-like structures early in development, reabsorbing them before they are born. The new fossil discoveries indicate that the mysticetes kept their teeth even longer than scientists had previously thought.

One fossil, named Willy, is particularly intriguing. Analyses of his teeth indicate that he could have chomped on sharks, Rivin said. And he’s surprisingly large, she added. Early baleen whales were thought to have been much smaller creatures and to have attained their famously gargantuan sizes only about 10 million years ago."

Always fascinating new surprises in Evolution!

KEEP UNSCIENTIFIC, RELIGIOUSLY-ORIENTED "CREATIONISM" AND "INTELLIGENT DESIGN" OUT OF OUR SCHOOLS - before the U.S. becomes the LAUGHINGSTOCK of the entire Scientific World!!!
